Hi guys,
I got a burning question. I am running apps like wifi master, du speed booster. Have scaled it across different traffic sources (4 in fact) and third tier geos to take advantage of the cheaper bids.
But I am only getting profits of low 2 figures daily.
I have split tested my lps and is running my best converting lp. Some days got profit while some days not. So it is rather fluctuating. I am not spending a lot daily as it is already negative ROI. How can I scale into 3 and 4 figures daily using app installs? Or is app installs dead with the low payouts?
Any advice from senior members?
Thank you.
App installs still work. Keep testing more campaigns/banner/lander. Once in a while you will find some good campaign which you can scale to 4-5figs easily.
Congrats on the green! Of course there's room to scale! 
1)More traffic sources: 4 aren't a whole lot! See here for more. And then see here for a LOT more!
2)More geos: How many geos have you tested? Asia (VN, ID, TH, MY, PH...), Africa (GH, KE, MA, EG, DZ, ZA...), and LATAM (CO, EC, PE, AR, CL...) have cheaper traffic that convert better than for developed countries. Get your banners and landers translated, set a low budget for each geo, identify the best ones and scale across traffic sources.
To save money on translation, pick languages that are spoken in many geos, e.g. Spanish (not the type spoken in Spain, but in LATAM America), Arabic for African geos, Vietnamese (VN) and Indonesian (ID) and Thai (TH), Chinese and English for some of the Asian geos (MY, SG...). I would definitely start with the first 5 languages.
3)More ad formats: Have you tested other banner sizes? Before you do, be sure to check the traffic source's ad planner to make sure they have enough traffic volume for a banners size before you bother with it. A lot of people don't bother with the less popular sizes, which makes that traffic cheaper. You can definitely take advantage of that if you're willing to put in the work of making banners in different sizes.
Caurmen's Mobile Cookbook: The Banquet has very valuable tips on scaling. I trust it will give you lots of ideas. 
Also: If you're finding that you're spending a lot of money in cutting a ton of traffic before you can get a campaign profitable, then it would be worth it to do further testing instead. Test more angles, more banner and lander variations. Improve your funnel so that you can make more of the traffic profitable, instead of trying to reach profits through cutting heavily. This way you can potentially spend less and make more.
Happy scaling!

What is the % ROI you are currently getting? Have you tried lowering your bids or negotiating a payout decrease with your traffic source if you buy more volume?
